@Marvin How can I run prefect deployment using Python using Prefect client

To run a Prefect deployment using Python with the Prefect client, you can use the

deploy

method on a flow. Here's a simple example based on the information I found: 1. Create a Deployment from Python Code: - You can create a deployment from your flow code by calling the

.deploy()

method on a flow. 2. Example Code:

python
   from prefect import flow

   @flow
   def my_flow():
       # Your flow logic here
       pass

   if __name__ == "__main__":
       deployment = my_flow.deploy(name="my_deployment")
       deployment.run()  # This will execute the deployment

3. Additional Context: - Ensure you have a

prefect.yaml

file in your directory if you are managing configurations through YAML. - You can also explore the

deploy.py

script from this GitHub source for more complex deployment scenarios. 4. Documentation Links: - Prefect Deployment Infrastructure Examples - Prefect YAML Deployment Concepts This should give you a basic understanding of how to execute a deployment programmatically using Prefect 3.x. If you have more specific requirements or configurations, you might need to adjust the code accordingly.

@Marvin I mean a Prefect deployment that has already been present

To run an existing Prefect deployment using Python, you can utilize the Prefect client to trigger the deployment. Here's a concise guide: 1. Use the Prefect Client: The Prefect client allows you to interact with Prefect's API to manage deployments, among other things. 2. Example Code:

python
   from prefect.client import get_client

   async def run_deployment(deployment_name: str):
       async with get_client() as client:
           deployment = await client.read_deployment_by_name(deployment_name)
           flow_run = await client.create_flow_run_from_deployment(deployment.id)
           print(f"Flow run created with ID: {flow_run.id}")

   if __name__ == "__main__":
       import asyncio
       asyncio.run(run_deployment("my-existing-deployment"))

3. Steps: - Import the Client: Use

get_client

to interact with the Prefect API. - Read the Deployment: Retrieve the deployment by its name using

read_deployment_by_name

. - Create a Flow Run: Use

create_flow_run_from_deployment

to trigger the deployment. 4. Documentation Links: - Prefect Deployment Infrastructure Concepts This approach allows you to execute a deployment that has already been configured and registered with Prefect. Adjust the deployment name in the code to match your specific deployment.
